The throttle_us member in the execbuf argument is now honored.
If the member is 0, no waiting for lag will occur, which
guarantees backwards compatibility with well-behaved clients.

Even if this bumps the version to 1 it does not mean the driver is
out of staging. From what we know this is the last backwards
incompatible change to the driver.

When time-based throttling is implemented, we need to bump minor.
When the old way of detecting scanout is removed, we need to bump major.
In the meantime, this change should not break existing user-space.

Use VRAM whenever there is free space for DMA buffers,
but use system GMR memory if using VRAM would cause an eviction.

This significantly reduces the guest system memory usage for
VMs with a large amount of VRAM allocated.

Currently we really only support S3, since the device doesn't support
saving of the 3D state.

On S3/S4, move all buffer objects to swappable memory and take down
GMR bindings. We need to do that from a PM notifier since we can't
do persistant memory allocations from the standard PM callbacks.

This was previously done explicitly for overlay- and fb buffers.
Now it's done for any buffer leaving the SYSTEM memory region.

Improve the command verifier to catch all occurences of surface handles,
and translate to SIDs.

This way DMA buffers and 3D surfaces share a common handle space,
which makes it possible for the kms code to differentiate.

This commit adds the vmwgfx driver for the VWware Virtual GPU aka SVGA.
The driver is under staging the same as Nouveau and Radeon KMS. Hopefully
the 2D ioctls are bug free and don't need changing, so that part of the
API should be stable. But there there is a pretty big chance that the 3D API
will change in the future.
